I-Firefox Community Forum

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

My entire Firefox account has disappeared, bookmarks, passwords, email, history, everything. I shut down my Mac Airbook when I left town Tuesday, powered up when I got home today and when i clicked on my Firefox icon at the bottom of the page, a new, unrecognizable Firefox page appeared asking for a signon rather than my default page, my email. Can you help me recover everything? Lloyd

thanks for looking into.

bold text all my passwords seem to have disappered on my desktop, I checked my mobie app and they were there. there was a message to sync this morning on sign in.

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

https://support.mozilla.org/en-US/questions/1569387#answer-1804235

My Firefox shortcuts keep disappearing: this is an almost daily occurrence. Sometimes they re-appear later without any intervention, sometimes they re-appear after a reboot. Right now, after rebooting and 'fixing' Firefox from Control Panel, they are still missing. I have 4 rows configured for both shortcuts and recent sites, and had 'pinned' about 20 shortcuts. Currently on Windows 10, soon to upgrade to Windows 11.

Can someone PLEASE tell me if there is a fix available for this (will it be resolved in Win 11?), or if there is a way to easily save and restore these backups when this problem occurs.

The ability to have 32 shortcuts is the motivating reason for my using Firefox over Chrome or Edge (which only allow 8), but if they keep disappearing like this I'm going to have to re-think my browser selection.

Thanks for any suggestions.

Windows10 simply multiplies the numbers of active Mozilla Firefox Apps which are open. Every day for about two weeks I've been having to delete hundreds of Firefox Apps open in the Task Manager. So many open in a very short time it locks up the Win10 system. I've attached a pic

Win10 will no longer let me download & transmit a .jpg file, sorry

Couple of updates back, Firefox quit working as before on a particular webpage. See attached images. Describing the webpage, this is from an embedded server on a Burk Arc Solo radio transmitter monitoring and control system. Accessing the webpage allows control over the transmitters in addition to getting readings on the performance of the units. The Edge browser shows how it's supposed to look, meter names and data values, they self refresh and show changes dynamically. Why is the Firefox no longer doing this? Note: this is at a remote site using remote desktop to access the machine watching the Burk. The machine is Windows 11.

Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:
